+## Checking if a Feature is Enabled or Disabled
+
+With GrowthBook, you can determine if a feature is on or off by checking the feature's value using different data types. A feature is considered off (i.e., is_on is false) under the following conditions, based on the data type:
+
+### String Feature
+
+If the feature value (regardless if it is default_value, force, or derived from an experiment) is an **empty string** or explicitly **OFF**, then is_on will be false.
+
+```rust
+let gb_url = "HTTP_OR_HTTPS_URL";
+let sdk_key = "SDK_KEY";
+let gb = GrowthBookClient::new(gb_url, sdk_key, None, None)?;
+
+let my_gb_feature = gb.feature_result(
+    "my_feature_string".to_string(),
+    Some(gb_attributes.clone()) // Optional: use attributes or set to None
+);
+
+```
+
+### Numeric Feature
+
+If the feature value is **0** (regardless if it is default_value, force, or derived from an experiment), then is_on will be false.
+
+```rust
+let gb_url = "HTTP_OR_HTTPS_URL";
+let sdk_key = "SDK_KEY";
+let gb = GrowthBookClient::new(gb_url, sdk_key, None, None)?;
+
+let my_gb_feature = gb.feature_result(
+    "my_feature_numeric".to_string(),
+    Some(gb_attributes.clone()) // Optional: use attributes or set to None
+);
+
+```
+
+### Object (HashMap) Feature
+
+If the feature value is an **empty object** (regardless if it is default_value, force, or derived from an experiment), then is_on will be false.
+
+```rust
+let gb_url = "HTTP_OR_HTTPS_URL";
+let sdk_key = "SDK_KEY";
+let gb = GrowthBookClient::new(gb_url, sdk_key, None, None)?;
+
+let my_gb_feature = gb.feature_result(
+    "my_feature_as_object".to_string(),
+    Some(gb_attributes.clone()) // Optional: use attributes or set to None
+);
+
+```
+
+### Array Feature
+
+If the feature value is an **empty array** (regardless if it is default_value, force, or derived from an experiment), then is_on will be false.
+
+```rust
+let gb_url = "HTTP_OR_HTTPS_URL";
+let sdk_key = "SDK_KEY";
+let gb = GrowthBookClient::new(gb_url, sdk_key, None, None)?;
+
+let my_gb_feature = gb.feature_result(
+    "my_feature_as_array".to_string(),
+    Some(gb_attributes.clone()) // Optional: use attributes or set to None
+);
